[System Design & Architecture: Scalability & Resilience](/quizzes/post/system-design-architecture-quiz) ## Advanced API Architecture & Design Patterns Up to 20 questions, shuffled on every run Quiz Configuration Enterto start Welcome to the Advanced API Architecture Quiz! This quiz will test your knowledge of advanced API design patterns, including REST, gRPC, webhooks, API versioning, caching strategies, pagination techniques, and enterprise patterns for scalable integrations. Each question is designed to challenge your understanding of how to build efficient APIs that scale with your applications. Good luck! Answer key and explanations20 questions The quiz above draws 20 questions at random from these 30, so a second attempt will not be the same run. Everything in the pool is listed here. 1. What is API versioning? AnswerA strategy for releasing new API features while maintaining backward compatibility for older clients 2. What is gRPC? AnswerA high-performance RPC framework that uses HTTP/2 for transport and Protocol Buffers for serialization 3. What is a webhook? AnswerA server-initiated callback where a server makes an HTTP request to a client-provided URL when an event occurs 4. What is pagination? AnswerThe practice of breaking large result sets into smaller, manageable chunks to improve API performance 5. What is cursor-based pagination? AnswerA method using opaque tokens to mark a specific position in a dataset rather than using row offsets 6. What is a caching strategy? AnswerA plan for storing frequently accessed data in high-speed storage to reduce overall response latency 7. What is an ETag? AnswerAn HTTP response header used as a unique identifier for a specific version of a resource 8. What is rate limiting? AnswerRestricting the number of requests a user can make within a specific timeframe to prevent abuse 9. What is a GraphQL subscription? AnswerA feature that allows clients to receive real-time messages from a server when specific data changes 10. What is an API gateway? AnswerA management layer that sits between clients and services to handle routing, security, and usage policies 11. What is the OpenAPI specification? AnswerA standard format for describing RESTful APIs to enable documentation, testing, and code generation 12. What is the difference between REST and SOAP? AnswerREST is a lightweight, stateless style using JSON, while SOAP is a rigid, XML-based protocol 13. What is the circuit breaker pattern? AnswerA design pattern that prevents an application from repeatedly trying to execute a failing operation 14. What is the bulkhead pattern? AnswerA pattern that isolates elements of an application into pools so that if one fails, the others continue 15. What is HATEOAS? AnswerA component of REST where the server provides links to other related actions in the response 16. What is the importance of API documentation? AnswerIt reduces developer onboarding time and helps prevent integration errors through clear usage guides 17. What is request/response validation? AnswerEnsuring that incoming payloads and outgoing data match the predefined schema and contract 18. What are timeout settings in APIs? AnswerConstraints that limit how long a server will wait for a response from a downstream dependency 19. What is the difference between API authentication and authorization? AnswerAuthentication verifies the identity of the user; authorization determines their specific permissions 20. What is API response compression? AnswerThe practice of shrinking the payload size using algorithms like Gzip to reduce transfer time 21. What is content negotiation in APIs? AnswerA mechanism that allows the client and server to agree on the best data format for the response 22. What is API tracing and correlation? AnswerAssigning unique IDs to requests to track their path across multiple distributed services 23. What is idempotency in APIs? AnswerAn API property where making the same request multiple times has the same effect as a single request 24. What are batch API operations? AnswerThe ability to perform multiple operations or updates within a single HTTP request 25. What is an API deprecation strategy? AnswerA plan for gracefully retiring old API versions while providing a transition path for users 26. How do you design APIs for mobile optimization? AnswerBy minimizing payload sizes and reducing the number of round-trips required for an action 27. What are Protocol Buffers (Protobuf)? AnswerA language-neutral, binary serialization format used for efficient data communication 28. What is API federation? AnswerAn architecture that allows multiple independent APIs to be exposed through a single interface 29. How are HTTP status codes categorized? Answer1xx (Informational), 2xx (Success), 3xx (Redirection), 4xx (Client Error), 5xx (Server Error) 30. What are common API rate limiting algorithms? AnswerStandard algorithms include Token Bucket, Leaky Bucket, and Fixed or Sliding Windows ## Tags [#API](/quizzes/tags/api)[#Architecture](/quizzes/tags/architecture)[#REST](/quizzes/tags/rest)[#GRPC](/quizzes/tags/grpc) ## Share [Facebook](https://facebook.com/sharer/sharer.php?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz "Share on Facebook")[Twitter](https://twitter.com/intent/tweet/?text=Advanced%20API%20Architecture%20%26%20Design%20Patterns&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz "Share on Twitter")[LinkedIn](https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz&title=Advanced%20API%20Architecture%20%26%20Design%20Patterns&summary=Master%20advanced%20API%20design%3A%20REST%2C%20gRPC%2C%20webhooks%2C%20API%20versioning%2C%20caching%20strategies%2C%20pagination%2C%20and%20enterprise%20patterns%20for%20scalable%20integrations.&source=https://mkabumattar.com "Share on LinkedIn")[WhatsApp](https://wa.me/?text=Advanced%20API%20Architecture%20%26%20Design%20Patterns%20https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz "Share on WhatsApp")[Telegram](https://t.me/share/url?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz&text=Advanced%20API%20Architecture%20%26%20Design%20Patterns "Share on Telegram")[Reddit](https://www.reddit.com/submit?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz&title=Advanced%20API%20Architecture%20%26%20Design%20Patterns "Share on Reddit")[Hacker News](http://news.ycombinator.com/submitlink?u=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz&t=Advanced%20API%20Architecture%20%26%20Design%20Patterns "Share on Hacker News")[Pinterest](https://pinterest.com/pin/create/button/?url=https%3A%2F%2Fmkabumattar.com%2Fquizzes%2Fpost%2Fadvanced-api-architecture-quiz&media=&description=Master%20advanced%20API%20design%3A%20REST%2C%20gRPC%2C%20webhooks%2C%20API%20versioning%2C%20caching%20strategies%2C%20pagination%2C%20and%20enterprise%20patterns%20for%20scalable%20integrations.
